Humans are changing global climate at a pace unprecedented in Earths history, but past climate trends can help us to understand where our current climate is headed. While we cannot make direct measurements of past atmosphere, we can use marine records preserved in the ancient plankton found on the sea floor. Lamont-Doherty scientists have been gathering ancient sea cores for over 50 years, producing a story of climate change and its affects.
Professor Bärbel Hönisch will discuss how we can use geological records to fine-tune our predictions for future global climate change.
